MILK-srnAInnn. 7

To all whom it may concern:

Be it known that I, ALnnnrM. LORENTZ, a citizen of the United States ofAmerica, and resident of McMechen, county of Marshall, and State of WestVirginia, have invented certain new and useful. Improvements inMilk-Strainers, of which'the following is a specification.

This invention relates to strainers for milk and other liquids, and ithas for its primary object to provide a simple, inexpensive, eflicientand sanitary strainer structure in which is employed a strainer clothand simple means whereby said cloth is removably secured in place. 7

A further object is to provide, in a strainer of. the charactermentioned, a strainer-cloth clamping and supporting device which may beconveniently introduced into and removed from operative position asoccasion requires; also to provide such a device which supports thestrainer cloth not only in a position in which a maximum area ofeffective straining surface is presented, but also in a position inwhich sediment or particles of foreign matter are effectually preventedfrom finding lodgment upon said straining surface or area.

In describing the invention in detail, ref erence is herein had to theaccompanying drawings, in which--' Figure 1 is a central verticalsection of the invention, and- Fig. 2 is a sideelevation of theremovable cloth support and clamp.

Referring to said drawings, 1 indicates the tapered body portion of afunnel-like casing having an'open upper end portion 2 and an open lowerend portion or flange 3, the latter being of reduced diameter and ofplain tubular form. A cylindrical metal ring 4 is adapted tobe-introduced within said tubular portion or flange 3 to a position inwhich a strainer cloth 5 is firmly clamped between it and said flange,said ring being made of such less external diameter than the internaldiameter of said flange that the accommodation of such cloth betweensaid elements is permitted.

A bail-like arch 6 having its opposite ends rigidly attached, as bysoldering, to said ring 4 at diametrically opposite points constitutes asupport over which the cloth is stretched and maintains the latter in anupright substantially conical position wherein it presents an effectivestrainlng surface of Specification 01 Letters Patent.

considerably greater area than that circumscribed by said ring 4. Due tothe fact that said arch rises to a considerable height above said ring,the said straining surface of the cloth is so sharply inclined thatparticles of foreign matter in the milk or other liquid being strainedwill not lodge on said surface, but will be carried into the acute angle7 formed between said cloth and said. casing.

In practice, the cloth 5 is laid loosely over the top of the arch 6 withthe outer edges of the former depending skirt-like below the lower edgeof the ring 4, after which the ring and cloth are together introducedupward through the tubular flange 3, the ring being. forced to its placewithin the embrace of said flange. Thus, the cloth is stretched throughfrictional engagement with the flange as it is forced upward through therestricted space between said flange and said ring. To remove the cloth,the ring is forced out of the embrace of the flange by downwardlydirected force applied to the top of the arch.

W hat is claimedis- 1. A strainer comprising a casing having an opensubstantially cylindrical lower end portion, a metal ring adapted to beremovably disposed within the embrace of said end portion, an uprightarch carried by said ring, and a strainer cloth overlying said arch andsaid ring and clamped between said ring and said end portion, said ringand cloth being adapted to be introduced to cloth clamping positionwithin said end portion through the bottom of the latter wherebystretching of thecloth is effected.

2. A strainer comprising a casing having an open lower end, a metal ringadapted for introduction within the embrace of said lower end, anupright arch carried by said ring, a cloth overlying said arch andhaving its edge portion clamped between said ring and said casing, saidarch supporting said cloth in a position presenting a substantiallyconical straining area, and said cloth being stretched by the act ofintroducing the archcarrying ring in an upward direction with the clothsupported thereon.

3. A strainer comprising a funnel-like casing having an opensubstantially cylindrical lower end portion, a ring adapted to beremovably mounted within said lower end portion, an upright arch carriedby said ring, a strainer cloth having its middle portion supported bysaid arch and having its outer edge portion depending about said ringand adapted to be firmly clamped be tween the latter and'said lower endportion, said ring being insertible through the bottom of said lowerendportion so that stretching of the arch-supported portion of the cloth iseffected by the act of inserting.
